Australia's top electricity and gas retailer Origin Energy said on Thursday its stake in the Australia Pacific LNG project (APLNG) reported a 45 per cent rise in second-quarter revenue, thanks to higher oil and spot LNG prices.

APLNG is a joint venture between Origin, ConocoPhillips and China Petroleum & Chemical Corp.

Origin, which controls nearly a third of Australia's energy retailing market, said revenue for the quarter ended Dec. 31 rose to A$740.9 million ($536.8 million) from A$509.8 million a year earlier.

Quarterly revenue from APLNG reached a record as 32 cargoes were shipped during the period.

In November, Origin said APLNG will get 350 petajoules of gas from the Queensland Curtis Liquefied Natural Gas project at an oil-linked price over 10 years from 2024 as part of infrastructure agreements between the two.

Origin's stock price fell steeply late last year amid a plunge in oil prices, but has risen about 11 per cent so far this year.
